Rock–Concrete Interface

Permeability under cyclic loads

For compressed air energy storage in abandoned mines, the permeability evolution of the interface under cyclic loading is experimentally characterized, providing key data for long-term sealing integrity.

Advantages

Cemented interface permeability: 10⁻¹³–10⁻¹² m²

Non-cemented interface permeability: 10⁻¹²–10⁻¹¹ m²

Higher inlet pressure leads to larger permeability increment ratio
